being had to the accompanying drawings, and

to the letters and figures of reference marked thereon, which form apart of this specification.

My invention relates to a, series of improved devices in asulky-plow,which willbe hereinafter fully described, and set forth in thespecification and claims.

Figure 1 is a side elevation, the right wheel being removed. Fig. 2 isaside elevation of.

the left side, the left wheel being removed. Fig. 3 is view partly insection of the apparatus for raising and lowering the land-wheel. Figs.4. and 5 are sections of the same. Fig. Fig. 7 is a top View of theseat-arch. Fig. 8 is a perspective of the oscillator through which theplow-beam passes and receives oblique adjustment. Fig. 9 is aperspective of the hanger attached to the crank or bail and supportingthe oscillator. Fig. 10 is a vertical section of the adj usting devicefor the land-wheel. Fig. 11 is a. vertical longitudinal section of theapparatus for raising and lowering the plow. Fig. 12 is a View of thesame apparatus as Fig. 11,- but partly in section, and showing theattachment of the quadrant to its support. Fig. 13 is a perspective ofthe quadrant cast in a single piece with the pfgvot for thelifting-lever and Fig. 14 is an inside view of the quadrant attached ,toits support and with the lifting-lever attached.

Fig.15is alongitudinal section oftheoscillator. A A are the wheels, Bthe seat-arch, and G the crank or ball to which the plow-beam is vpivoted; D the plow-beam, E the mold-board,

and 2. The crank or bail G is disconnected from the axle, and has itsbearings in the seatarch at O 1 Fig. 6, and is connected to thehand-lever N by means of the lifting-lever K, straps L, and bar M. Whentheplow is down to-its work the bail lies in a horizontal position, asseen in Fig. 2,in consequence of being pivoted above the beam D, insteadof below, as usual. So it will be readily seen that when .the bail israised but slightly above the horizontal by means of the hand-lever Nand its connecting mechanism the draft at the end of the beam assists toraise the plow. -The plow-beam D passes through a wedge-shaped hole inthe oscillator J, as seen in Fig. 15,

-(the oscillator is plainly shown in Fig. 8,) the front portion of theoscillator fitting the beam closely, and flaring rearwardly, where it isprovided with the set-screws R R for oblique adjustment and to hold thebeam when adjusted. The lower'end of the hanger I hasa pivotal socketedbearing, S, upon which the hole T in the oscillator J rests, and is heldin place by means of a bolt, U, Figs. 1 and 2. end of the oscillator hasthe curved slot V, Fig.

8, which passes over the screw-bolt W, Fig. 9,;

and is held in place by nut Y, Fig. 2. The corrugations X X, Figs. .8and 9, hold the oscillator firmly in place when adjusted.

The upper Thus it willbc seen that the oscillator, Fig. v

8, serves the double purpose of adjusting the plow both obliquely andlaterally, the, ob-

lique adjustment of the plow being effected by; means of the set-screwsR R at the rear part of the oscillator, and the lateral adjustment orswinging ot' the plow effected through the means of the slot V and thepivot S on the lower end of the hanger I, the corrugations X X on theoscillator and hanger holding all firmly when adjusted. In myconstruction there is no lateral adjustment at the clevis required, thewhole being accomplished at the bail through the means of thewedge-shaped hole in the oscillator and the set-screws It It, ae seen inFig.15. Neither do I require a jointed tongue to govern the land of theplow. The draft being in a straight line, the

wheels do'not incline to drag sidewise, as whenthe adjustment of theland is accomplished through the means of a jointed or adjustabletongue. r 1

through clamp X.

The seat-arch is provided with two socketed bearings, Z Z, for thetongue-timbers A A. When the sulky is to be used with two draftanimalsthe tongue is bolted beneath the middletongue-timber, A,and when threeanimals are to be used the tongue is bolted to the other timber, A. InFig. 1, A is seen, and in Fig. 2, A. By reference to Fig. 6 it will beseen that A may be placed in the center socket, Z, and A placed in theouter or left-hand socket, Z.

The quadrant A Fig. 13, is cast in a single piece, ready for use, andprovided, in addition to the usual notches in the periphery, with aseriesofholes, P,in conjunction with the notches R. A pin, S, isprovided and held in place by means of a nut, T, as seen in Fig.1. Whenthe plow is to be locked in the ground the pawl Y falls into the notchesin the periphery of the quadrant, and requires attention to see that thepawl is placed in the same notch each time after raising the plow.

By means of the holes P and pin S the operator, after having determinedthe depth at which it is intended to plow, may place the pin S in a holeaccordingly, and throw the lever down until it strikes the pin and letsgo the latch without any care as to which notch it will fall into.

The quadrant is provided with a lug or hearing, U, and cleats V V, asseen in Fig. 13. The cleats V V embrace the tongue timber or bar A, andthe lug U forms the pivot for the liftingdever, the whole being heldfirmly in place by means of. a single bolt-,W. The clamp X connects thelovers M N by means of the boltBpassing through thewhole. Thisclamp Xcarries the pawl Y, which falls into the notches in the quadrant, asseen in Figs. 12 and 14. The pawl is connected to the latch D by meansof the rod 0. The spring on the latch throws the pawl down into thenotches in the periphery of the quadrant.

By reference to Fig. 11 it willbe seen that the bolt B passes throughthe levers M Nand The lip A of clamp X falls down on the inside'of thequadrant and prevents thelever from slipping 011' of the stud U of thequadrant. The pawl Y slides in a. recess in clamp X. Thus it will beseen that a single bolt, 15, holds levers M N, clamp X, and through saidclamp the pawl Y, and also holds the lever on the stud U by means of thelip A falling down on the inside of the quadrant. A single bolt, W,holds the quadrant firmly in place, as seen in Figs. 11 and 12, by meansof the cleats V V elaspin g the timber A.' Thus the two bolts B and Whold in place the entire lifting mechanism.

The clamps E are attached to the bail on either side of the hanger I,for the purpose of parallel lateral adjustment of the plow to adapt itto two or three draft-animals or other circumstances.

The foot-rest L extends back beneath the center tongue-bearing, and thebolts M pass upward through the rearend. of the foot-rest to hold it inplace, and through the slots 1? of the bearings Z, through the tongue-timber A, and up through the seat-spring N which spring supports theseat 0 The seat-arch is cast in a. single piece with the variousbearings, cast as integral parts thereof, as shown in Figs. 6 and 7,with the vertical part R upon which the land-wheel mechanism slides upand down to adjust the sulky to the depth of furrow required, and withthe slots 1? for the bolts which hold the tongue-timbers. As the patternparts in the middle, these slots 1? may be cast and avoid the necessityof drilling holes for the bolts. Thus the seat-arch is cast ready foruse without anydrilling or fitting whatever. rugations to support theland-wheel in position when adjusted, are shown in Figs. 3-and 4.

The hollow bearings P and S for the bail and the lifting-lever for theland-wheel are shown in section at Fig. 10. The bearing 0, Fig. 6, isprovided with a cap, T, as seen in. Fig. 2. The land-wheel A is placedupon the spindle U Figs. 3 and 5, the spindle being attached to theslide V, which slide moves up and down on the part R of the seat-arch.The set-screw W performs the double oftice of holding the spindle U inplace and also the lifting-bar X which lifting-bar is connected to thecrooked lever Y by means of a socketjoint, as best seen in the section,Fig. 10,whero it will be seen that there is no strain on the bolt,except to hold the parts together. The lever Y is pivoted on the hollowbearing S of the seat-arch, and held upon the hearing by means of thebolt B By means of the lever Y and the lifting-bar X the slide Vcarrying the spindle U is raised and lowered, and held in position bymeans of corrugations, as shown in Fig. 4, where the corrugations areheld in contact by means of the cam-lever 0 which cam operates upon thecorrugated block D to press it in contact with the part B of theseatarch, as seen in Figs. 4 and 5. The part B of the seat-archcontaining the corrugations is sloped or beveled, as seen in Fig. 5, andthe corrugated block D is sloped to match, the sloping of these partsbeing for the purpose of clamping the slide V more rigidly to theseat-arch to prevent the land-wheel from wriggling. By this constructionthe land-wheel is held as firmly to the seat-arch as therfurrow-wheel.

When it is necessary to raise or lower the slide V and axle thecam-lever G is thrown up, and a lug, F attached to the cam, strikes alag, E attached to the block D and withdraws the teeth of the block ll)from the teeth of the part B of the seat-arch, and allows the slide V toplay freely up and down on the part B of the seat-arch, and when theslide V is adjusted the cam-lever O is pressed downward and the wholefirmly clamped together, the whole mechanism being cast ready to gotogether without fitting.
